Poured my heart out to ex, she saw message, no response

It has not been all that long - only about 12 hours. But, still, she saw my message, didn't respond, signed off, then came back on and did some other activity all over Facebook. And still didn't respond. I'm worrying a bit here. It was a very long message I sent, but no response at all?
